SPECIFICATION forming part of Letters Patent No. 791,120, dated'May 30,19 05. Application filed April 30, 1904. Serial No. 205,647.

To all whom it may concern.-

Be it known that I, SooTT M. ABBOTT, a citizen of the United States,residing at Watertown, in the county of Carver and State of Minnesota,have invented certain new and useful Improvements in Heating-Drums, ofwhich the following is a specification, reference be-. ing had thereinto the accompanying drawings, in which- Figure 1 is a plan view of thepreferred form of drum; Fig. 2,'a longitudinal vertical sec-, tionalview taken on the line II II of Fig. 1; Fig. 8, a horizontal sectionalview on the line III III of Fig. 2; Fig. 4, a vertical sectional view onthe line IV IV of Fig. 2 through the smoke-flue; Fig. 5, a similar viewshowing the damper open and the stovepipe connected to the lower end ofthe smoke-flue; Fig. 6, a plan view of a slightly different form ofdrum; Fig. 7, a vertical sectional view on the line VII VII of Fig. 6;Fig. 8, a plan View of still another form of drum, and Fig. 9 a verticalsectional view on the line IX IX of Fig. 8.

One of the main objects of this invention is to provide an efficientheating-drum of'simple construction which may be connected to thesmoke-pipe of a stove and the heat of the waste gases utilized to heatthe air of an ad joining room or of the same room in which the stove islocated.

A further object of the invention is to provide such a heating-drum ofsimple construction which may be cheaply manufactured and which isadapted for use in several positions.

A further. object of the invention is to provide the drum with suitabledraft-directing devices by which thesmoke and hot gases may be directedaround the drum or be permitted to pass directly through it withoutinterfering with the draft of the stove.

Other important objects and advantages of the invention will appearhereinafter.

Referring to various parts by numerals, l designates the outer verticalcasing, which is shown cylindrical, but which, of course, it will beunderstood, may be of any desired shape in cross-section. The casing isprovided with the end pieces or caps 2. Extending through the casing isa large vertical radiating-flue 3, and between said flue and the in nersurface of the casing 1 is located a smokeflue 4, said flue entirelyclosing said space, as shown clearly in Fig. 3; This smoke-flue is incommunication with the radiating-flue 3 through an opening 5, and thesmoke-pipe 6 from the stove extends into radiating-flue 3 andconnects-with the smoke-flue through the said opening 5, as clearlyshown in Fig. 2. When the heating-drum is located above the stoveforinstance, on the floor above-the smoke-pipe enters the radiating-fluefrom below. When, however, it is located on the same floor as the stove,the smoke-pipe may enter the radiatingflue 3 from above, as shown indotted lines in Fig. 2.

Extending through the drum are two openended radiating-flues 7, one oneach side of the smoke-flue. Substantiallyv midway its ends a horizontalpartition 8 is provided, which divides the casing 1 into a lowercompartment 9 and an upper compartment 10, these com-' partmentsconnecting through an opening 11 in said partition, said opening beinglocated adjacent the smoke-pipe. The smoke-pipe is provided near itslower end with an opening 12, which is in communication with the lowercompartment of the drum, said opening being opposite the opening 11through the partition 8, the object being to cause the smoke and hotgases entering compartment 9 through the opening 12 to pass entirelyaround said compartment before reaching the opening 11. Above thepartition 8 the smoke-pipe is provided with a second opening 13, saidopening being also through the side of the smoke-pipe opposite theopening 11, so that the hot gases rising through the opening 11 in thepartition from compartment 9 must pass entirely around the flue 3 beforeit can reenter the smoke-pipe through said opening 13. Mounted in thesmoke-pipe between the openings 12 and 13 is a damper 1 1, which may beof any suitable construction. The purpose of this damper is obvious.When it is desired that the smoke shall pass directly through thesmoke-flue without entering the drum, this damper is placed in its openposition, as shown in Fig. 5. When it is closed, the smoke and gasesmust pass aroundthe drum twice before escaping up the smoke-flue.Connected to the upper side of the damper by means of a rod is a gate orclosure 16, which is hinged at the lower end of the opening 13 and isadapted to be swung upward to close the said opening when the damper 14is placed in its open position. This gate when it is closed prevents anycirculation of hot gases and smoke around the drum and insures a directdraft through the smoke-flue. The drum is provided with suitablesupporting-legs 17.

It will of course be understood that the smoke-pipe from the stove mayenter the smoke-flue through the side of the casing 1 instead of beingcarried into the main radiating-flue 3. I prefer, however, to connect itas shown in Fig. 2, as the hot stovepipe will assist materially inheating the air in said main radiating-flue and will thereby materiallyincrease the upward flow of air through said flue. The radiating-Huesare all vertically disposed for the purpose of creating a circulation ofair in the room in which the heating-drum is placed.

In Fig. 2 the lower end of the smoke-flue is closed by means of a cap18; but it is obvious that, if desired, the smoke-pipe from the stovemay be connected to the lower end of this flue and the cap placed in theopening 5, as shown in Fig. '5.

In the form of drum shown in Figs. 6 and 7 the smoke-pipe 4* is arrangedin the main radiating-fiue and is connected to the lower and uppercompartments of the main casing through openings 13 and 12, saidsmoke-flue being provided with a damper device 14 similar to the dampershown in Figs. 2 and 4:. The lower end of the smoke-flue is preferablyclosed by a removable cap 18 and the smokepipe from the stove connectedto the side of said flue between the openings 12 and 13*. Partition 8 inthis form of the drum is provided with an opening 11 to permit of thecirculation of the hot gases.

In the form of drum shown in Figs. Sand 9 the large main radiating-flueis dispensed with and three small radiating-fines are employed. Thesmoke-flue 4 is connected to the smoke-pipe from the stove through anopening 5 in the side of the casing. .This smokeflue is provided withopenings 12 and 13 and with a damper device 14 which operates in amanner similar, to the damper device and openings shown in Fig. 7. Thepartition 8 is provided with an opening 11 From the foregoing it will bereadily seen that I provide a heating-drum of exceedinglysimpleconstruction which is well adapted for utilizing the smoke and hot gasesfrom a stove for heating the air in a room above the stove or for use inthe same room with the stove or in another room on the same floor. Itwill also be readily seen that the device may be 'cheapl y manufactured.

Having thus described my invention, what I claim is 1. Aheating-drumcomprising,an outer casing, a main radiating-flue extending verticallytherethrough, a smoke-flue extending vertically therethrough and forminga divisionwall between one side of the radiating-flue and the adjacentwall of the casing and having two openings formed therein, a horizontalpartition dividing the easing into upper and lower compartments andformed with an opening therein, one of the openings in the smokefluecommunicating with the upper compartment and the other communicatingwith the lower compartment, and a damper by which the smoke may becaused to circulate through the compartments of the casing.

2. A heating-drum comprising, an outer casing, a plurality of verticalradiating-fines extending therethrough a smoke-flue extending verticallytherethrough and forming a division-wall between one of theradiating-fines and the adjacent wall of the casing and having twoopenings formed therein, a horizontal partition dividing the easing intoupper and lower compartments and formed with an opening therein, one ofthe openings in the smoke-flue communicating with the compartment abovethe horizontal partition and the other communicating with thecompartment below said partition and a damper by which the smoke may becaused to circulate through the compartments.

3. A heating-drum comprising, a main casing, a main radiating-flueextending vertical] y therethrough, a smoke-flue in communication withsaid main radiating-flue, a horizontal partition in the casing dividingit into an upper and lower compartment and provided with an opening, andmeans for causing the smoke and hot gases to pass through both of saidcompartments, and a plurality of vertical radiating-flues.

In testimony whereof I hereunto afiix my signature, in the presence oftwo witnesses, this 5th day of April, 190 i.
